Imaging findings
CT reveals a soft tissue nodule encasing the left internal mammary artery, which was clearly new compared to a 10-year-old prior study before her mastectomy. This was an isolated finding without other evidence of recurrence.
Key takeaways
In patients with a history of breast cancer, particularly those with medial tumors or increased axillary node involvement, it is important to include the internal mammary lymph node chains in the search pattern for potential metastatic recurrence. While isolated metastases in this region are uncommon, they can occur.
